MetabolomicsMicrobiome-produced nicotinic acid controls colon regional identity and injury susceptibility

Regional structure of the intestinal epithelium is critical for its function and is associated with the risk of specific gut diseases. However, how regionalization is established and how it influences disease susceptibility remains poorly understood. Here, we investigated the role of the gut micr...

MetabolomicsAge-, sex- and proximal-distal-resolved multi-omics identifies regulators of intestinal aging in non-human primates.

The incidence of intestinal diseases increases with age, but the regulators of gut aging and the molecules linking gut aging and diseases remain largely unknown. By profiling the transcriptome, proteome, phosphoproteome and metabolome of 104 Macaca fascicularis large intestinal tissues, ...

TranscriptomicsExpression data for 52 microsatellite stable (MSS) primary tumors from patients with proximal colon cancer.
Samples were taken from surgically resected tumor specimens from patients with proximal colon cancer. The expression profiles were determined using the Affymetrix GeneChip Human Exon 1.0 ST Array version 2. APC gene mutation status was determined using Sanger sequencing. A classifier for APC mutatio...

ProteomicsQuantitative proteogenomic characterization of inflamed murine colon tissue using an integrated discovery, verification, and validation proteogenomic workflow
Rag2-/-Il10-/- mice were subjected to infection by Helicobacter hepaticus and allowed to develop long-term infections. Proximal colon tissue was then harvested from the mice for analysis. RNA was isolated from the samples and submitted for transcriptomic analysis; this data was then used to create a...

TranscriptomicsResistant starch induces catabolic but suppresses immune and cell division pathways and changes the microbiome in proximal colon of male pigs
Consumption of resistant starch (RS) has been associated with various intestinal health benefits, but knowledge on its effects on global gene expression in the colon is limited. The main objective of the current study was to identify genes affected by RS in the proximal colon to infer which biologic...

TranscriptomicsNormal mucosa of Proximal Colon (i.e. proximal to hepatic flexure) versus normal mucosa of Terminal ileum Transcriptomes (Affymetrix array U133A) in colon cancer patients
Proximal Colon (i.e. proximal to hepatic flexure) versus Terminal ileum Transcriptomes (Affymetrix array U133A). All subjects were operated on for proximal-colon tumor (biopsies of proximal-colon normal mucosa were made at more than 5 cm from the site of the tumor).

TranscriptomicsGlobal gene expression profile of colon from wild-type and AE2-knockout mice.
The objective of this study was to identify changes in gene expression levels between wild-type and AE2-knockout colon. 7 wild-type and 7 AE2-null colon RNA samples were compared to identify genes that are differentially expressed in the colon of AE2 knockout mice. Total RNA was collected from both ...

ProteomicsMembrane proteomis profile along human colon
The colonic epithelium is a highly dynamic system important for regulation of ion and water homeostasis via absorption and secretion, and in maintaining a protective barrier between the outer milieu and the inside of our body. These processes are known to gradually change along the length of the col...

TranscriptomicsRNAseq analysis of colon and ileum tissue from naive wild type, MR1-/- and IL-17A-/- mice
Determination of differentially expressed genes in the proximal colon and distal ileum tissue in MR1 and IL-17A deficiency at steady-state. Tissue from naïve mice was harvested, total RNA extracted and subjected to RNASeq analysis.
